Questions & explanations
1. In a puzzle cache, you find a series of numbers: 33 36 38 36 33 32. What is a likely pattern, and how might it lead to coordinates?
Those numbers could be the differences between letters. For instance, if you start with a baseline letter and add each number, you get a sequence. Or they might be ASCII codes (but those are usually larger). More commonly, they are the number of letters in each word of a hidden message: e.g., 'three six eight six three two' would be '3 6 8 6 3 2', but that's not it. Another guess: they are the letters' positions in the alphabet (A=1, B=2... so 33 is not valid). Perhaps they are a code like 'A=1, B=2' but shifted: 33 - 32 = 1 = A, so 33=A, 36=D, 38=F, 36=D, 33=A, 32=Z? That spells 'ADFDAZ' which is nonsense. Alternatively, they could be numbers to form coordinates like N33 36.386, W... But that's unlikely. The best way is to look for a hint in the cache description. Often these numbers are the differences between actual coordinates and a starting point.
2. How do you register a PLB and why is it important?
You register a PLB with your country’s rescue authority, such as the National Oceanic and Atmospheric Administration (NOAA) in the United States or the National Search and Rescue Secretariat in Canada. During registration, you provide your name, emergency contacts, and description of your typical activities. This information is stored in a database that rescuers can access when your beacon activates. Registration helps rescuers know who they are looking for and how to contact your family. If you move or change phone numbers, you must update your registration. An unregistered PLB can still work, but it delays rescue because rescuers have no background information.
3. What do contour lines on a map represent?
Contour lines are brown lines on a topographic map that connect points of equal elevation above sea level. Each line represents a specific height, so if you walk along a contour line, you stay at the same elevation. The spacing between lines shows steepness: closely spaced lines mean a steep slope, widely spaced lines mean a gentle slope. Contour lines never cross each other, and they form V-shapes pointing uphill in valleys and pointing downhill on ridges. By reading contour lines, you can visualize hills, valleys, and flat areas without seeing them. The contour interval is the vertical distance between lines, often 10 meters or 20 feet.
4. What should you do first if you need to activate an emergency beacon?
First, make sure your situation is truly an emergency, such as a life-threatening injury or being hopelessly lost. Then turn on the beacon and extend its antenna if it has one (for PLBs). Press and hold the SOS button until the device confirms activation, often with a flashing light or beep. Stay in the same location if possible, because rescue teams will home in on your signal. If you can, cover the device to protect it from weather but keep it upright with a clear view of the sky. Do not turn off the beacon until rescuers arrive or you are safe. If you have a satellite messenger, you may also send a message explaining your situation.
5. How can you estimate the height of a hill using contour lines?
First, find the contour interval, usually written in the map legend (for example, 10 meters). Then look at the index contours, which are darker lines labeled with elevation numbers. Count the number of contour lines from a known elevation to the top of the hill. For instance, if the base is at 200 meters and the top is 5 contour lines higher with a 10-meter interval, the height is 250 meters. Remember that the top may be a closed loop without a number, so you estimate it as the next interval. Always double-check by looking at the index contours near the summit. This skill helps you gauge the difficulty of a climb.
6. Why do satellite messengers require a subscription plan, but PLBs do not?
Satellite messengers use commercial satellite networks that charge for data transmission. The subscription covers the cost of sending text messages and tracking your location. Without a plan, the messenger cannot connect to the satellite network. PLBs use a government-owned satellite system (like COSPAS-SARSAT) that is free for emergency use. Since PLBs are only for emergencies, there is no ongoing fee, but you must register the device. The trade-off is that PLBs have no messaging or tracking capabilities. Choose a messenger if you want regular contact; choose a PLB for a simple, no-fee emergency device.
7. What is the International Orienteering Federation (IOF)?
The International Orienteering Federation, or IOF, is the global organization that governs the sport of orienteering. It was founded in 1961 to unite national orienteering bodies and set common rules. The IOF is based in Finland and has member federations from many countries worldwide. It works to promote orienteering and organize international competitions like the World Orienteering Championships. The IOF also helps develop the sport by providing training and support to new regions. Its structure includes a General Assembly, Council, and various committees focused on different aspects of the sport.
8. What should you do if someone is struck by lightning?
Call for emergency help immediately. The person may have burns, nerve damage, or have stopped breathing. Check if they are conscious and breathing. If not breathing, start CPR right away because lightning victims often recover if given prompt care. Do not worry about electric shock from touching them; they are safe to touch. Move them to a safer place if possible, but only if the area is still dangerous. Cover them with a blanket to prevent shock, but do not remove burned clothing. Continue CPR until help arrives. Lightning strikes can also cause broken bones from falling, so handle gently.
9. Why has orienteering not been included as a full Olympic sport?
Orienteering has faced challenges for full Olympic inclusion. One reason is that the sport requires large natural areas and complex map preparation, which can be hard to set up in an Olympic venue. Another is the difficulty of making the race exciting for spectators and TV viewers, as athletes run through forests out of sight. The Olympic program is also very limited, so new sports face strong competition. Additionally, orienteering's governing body has to meet strict criteria for global participation and gender balance. Despite these hurdles, efforts continue to improve the sport's appeal.
10. What does a closed circle of contour lines mean on a map?
A closed circle of contour lines represents a hill or a mountain top. The innermost line is the highest elevation, and the lines around it show decreasing height. If there is a small dot inside the circle, it often marks the exact summit. Sometimes there are smaller closed circles within a larger one, indicating a peak. If the circles have hachure marks (short lines pointing inward), it is a depression, not a hill. So check the elevation numbers: if they increase toward the center, it is a hill; if they decrease, it is a depression. On most maps, hills are common and depressions are rare.
11. What is a safe shelter during a lightning storm outdoors?
A fully enclosed building with walls and a roof is the safest shelter. If no building is available, a hard-topped metal vehicle with the windows up is very safe because the metal frame directs lightning around the occupants. Avoid open shelters like picnic pavilions, tents, or small sheds because they offer no protection. Do not lie on the ground; instead, crouch on the balls of your feet with your head low and hands over your ears. Stay away from tall objects like trees, poles, and cliffs. The goal is to minimize your height and contact with the ground to reduce your chance of being hit.
12. What is the 30/30 rule for lightning safety?
The 30/30 rule says: if you see lightning and count to 30 before you hear thunder, you are within danger range and should go to a safe shelter. Wait at least 30 minutes after the last thunder before leaving shelter. The count uses the difference between seeing lightning and hearing thunder. Sound travels about 1 mile in 5 seconds, so 30 seconds means the lightning is about 6 miles away. But lightning can strike far from the storm, so go to shelter as soon as you hear thunder. The 30-minute wait ensures the storm has moved away enough. This rule helps reduce the risk of being hit.
